The Tesla Model S Long Range Plus has officially received a 402-mile range rating from the Environmental Protection Agency, according to the FuelEconomy.gov website.
The Model S Long Range Plus received a 391-mile rating from the EPA in April, but the test was flawed CEO Elon Musk said.
“It should be said that the real Model S range is 400 miles,” Musk said during the Q1 Earnings Call on April 29. “But when we did the last EPA test, unfortunately, the EPA left the car door open and the keys in the car.”
The Long Range Plus has around 5% more efficiency compared to the 2020 Long Range model. The Tesla team stated in a blog posting that mass reduction, new “Tempest” Aero Wheels and Tires, increased efficiency of the drive unit, and regenerative braking improvements contributed to the Model S Long Range’s increased driving distance.
The Model S Long Range Plus utilizes a 100 kWh battery pack to power its extended travel capabilities. However, the car isn’t just suitable for long trips; it also packs a punch. With a 155 MPH and 0-60 time of 3.7 seconds, the Model S Long Range Plus will also satisfy the speed needs of anyone who requires an extra thrill.
While Musk was right about the real range capabilities of the Model S Long Range, the accomplishment is a testament to Tesla’s battery tech developments that have been a primary focus of the electric automaker for years.
Tesla has worked toward developing its own high-tech battery cells to achieve long-lasting and affordable packs for its vehicles and energy storage systems. After working with Jeff Dahn and his team of battery researchers and acquiring companies like Maxwell Technologies and Hibar Systems, Tesla made significant strides toward developing in-house cells that will revolutionize electric mobility.
The company plans to outline its new battery developments and technology discoveries at its “Battery Day” in September.
Tesla continues to push toward the improvement of its battery packs by utilizing different electrolyte solutions and electrode makeups. The company continues to submit patents that describe advances in the efficiency and performance of its battery packs.
Another focus of Tesla’s battery developments is eliminating the use of cobalt from its cells. Cobalt is effective in maintaining cycle stability in lithium-ion cells, but it is controversial due to its mining and labor practices. Tesla utilizes a series of third-party due diligence measures to ensure that the cobalt used in its batteries is responsibly sourced.
Although cobalt will eventually be removed from Tesla’s batteries, the company did sign a multi-year deal with Swiss-based Glencore to fulfill its needs for the mineral at Giga Berlin and Giga Shanghai.
The inclusion of the 402-mile range rating on the FuelEconomy.gov website is symbolic of Tesla’s sizeable lead in battery tech and efficiency. The company continues to improve the range of its vehicles through cell developments and software updates, and “Battery Day” will likely reveal what Tesla has been working toward behind the scenes for its “Roadrunner” project.

Tesla Cybercab tests are going on overdrive with production-ready units
Tesla is ramping its real-world tests of the Cybercab, with multiple sightings of the vehicle being reported across social media this week.
Tesla is ramping its real-world tests of the Cybercab, with multiple sightings of the autonomous two-seater being reported across social media this week. Based on videos of the vehicle that have been shared online, it appears that Cybercab tests are underway across multiple states.
Recent Cybercab sightings
Reports of Cybercab tests have ramped this week, with a vehicle that looked like a production-ready prototype being spotted at Apple’s Visitor Center in California. The vehicle in this sighting was interesting as it was equipped with a steering wheel. The vehicle also featured some changes to the design of its brake lights.
The Cybercab was also filmed testing at the Fremont factory’s test track, which also seemed to involve a vehicle that looked production-ready. This also seemed to be the case for a Cybercab that was spotted in Austin, Texas, which happened to be undergoing real-world tests. Overall, these sightings suggest that Cybercab testing is fully underway, and the vehicle is really moving towards production.
Production design all but finalized?
Recently, a near-production-ready Cybercab was showcased at Tesla’s Santana Row showroom in San Jose. The vehicle was equipped with frameless windows, dual windshield wipers, powered butterfly door struts, an extended front splitter, an updated lightbar, new wheel covers, and a license plate bracket. Interior updates include redesigned dash/door panels, refined seats with center cupholders, updated carpet, and what appeared to be improved legroom.
There seems to be a pretty good chance that the Cybercab’s design has been all but finalized, at least considering Elon Musk’s comments at the 2025 Annual Shareholder Meeting. During the event, Musk confirmed that the vehicle will enter production around April 2026, and its production targets will be quite ambitious.

Tesla gets a win in Sweden as union withdraws potentially “illegal” blockade
As per recent reports, the Vision union’s planned anti-Tesla action might have been illegal.
Swedish union Vision has withdrawn its sympathy blockade against Tesla’s planned service center and showroom in Kalmar. As per recent reports, the Vision union’s planned anti-Tesla action might have been illegal.
Vision’s decision to pull the blockade
Vision announced the blockade in early December, stating that it was targeting the administrative handling of Tesla’s facility permits in Kalmar municipality. The sympathy measure was expected to start Monday, but was formally withdrawn via documents sent to the Mediation Institute and Kalmar Municipality last week.
As noted in a Daggers Arbete report, plans for the strike were ultimately pulled after employer group SKR highlighted potential illegality under the Public Employment Act. Vision stressed its continued backing for the Swedish labor model, though Deputy negotiation manager Oskar Pettersson explained that the Vision union and IF Metall made the decision to cancel the planned strike together.
“We will not continue to challenge the regulations,” Petterson said. “The objection was of a technical nature. We made the assessment together with IF Metall that we were not in a position to challenge the legal assessment of whether we could take this particular action against Tesla. Therefore, we chose to revoke the notice itself.”
The SKR’s warning
Petterson also stated that SKR’s technical objection to the Vision union’s planned anti-Tesla strike framed the protest as an unauthorized act. “It was a legal assessment of the situation. Both for us and for IF Metall, it is important to be clear that we stand for the Swedish model. But we should not continue to challenge the regulations and risk getting judgments that lead nowhere in the application of the regulations,” he said.
Vision ultimately canceled its planned blockade against Tesla on December 9. With Vision’s withdrawal, few obstacles remain for Tesla’s long-planned Kalmar site. A foreign electrical firm completed work this fall, and Tesla’s Careers page currently lists a full-time service manager position based there, signaling an imminent opening.
Tesla Semi Program Director Dan Priestly teased the major improvements to the all-electric Class 8 truck on Thursday night, following the company’s decision to overhaul the design earlier this year.
Priestley said he drove the Semi on Thursday, and the improvements appear to be welcomed by one of the minds behind the project. “Our customers are going to love it,” he concluded.

The small detail does not seem like much, but it is coming from someone who has been involved in the development of the truck from A to Z. Priestley has been involved in the Semi program since November 2015 and has slowly worked his way through the ranks, and currently stands as the Director of the program.
Tesla Semi undergoes major redesign as dedicated factory preps for deliveries
Tesla made some major changes to the Semi design as it announced at the 2025 Annual Shareholder Meeting that it changed the look and design to welcome improvements in efficiency.
Initially, Tesla adopted the blade-like light bar for the Semi, similar to the one that is present on the Model Y Premium and the Cybertruck.
Additionally, there are some slight aesthetic changes to help with efficiency, including a redesigned bumper with improved aero channels, a smaller wraparound windshield, and a smoother roofline for better aero performance.
All of these changes came as the company’s Semi Factory, which is located on Gigafactory Nevada’s property, was finishing up construction in preparation for initial production phases, as Tesla is planning to ramp up manufacturing next year. CEO Elon Musk has said the Semi has attracted “ridiculous demand.”
The Semi has already gathered many large companies that have signed up to buy units, including Frito-Lay and PepsiCo., which have been helping Tesla test the vehicle in a pilot program to test range, efficiency, and other important metrics that will be a major selling point.
Tesla will be the Semi’s first user, though, and the truck will help solve some of the company’s logistics needs in the coming years.
